How Often To Service Juki Sewing Machine?

Juki sewing machines are some of the most popular on the market, known for their durability and reliability. But like any machine, they require regular maintenance to keep them running smoothly. How often you need to service your Juki sewing machine depends on how often you use it and what type of sewing you do.

In this article, we’ll be discussing how often should you clean your Juki Sewing Machine and also ways how to clean it without causing more harm than good.

How Often To Service Juki Sewing Machine?

Cleaning your sewing machine is very essential to how long you want it to last. A general rule of thumb dictates that you service your Juki sewing machine every 6 to 12 months. However, if you’re the kind of person that does heavy-duty sewing, then it’s advisable to service your sewing machine frequently like every 2 – 3 months.

If you use your Juki sewing machine occasionally, you can get away by just servicing it once a year. However, you have to make sure the components are regularly oiled to avoid corrosion or rust setting in. 

Another thing to take into consideration when it’s time to service your Juki sewing machine is that you have to take it to a qualified technician. Do not attempt to service it yourself if you do not have an understanding of the inner components of a Juki sewing machine.

How Often Should I clean Juki Sewing Machine?

Cleaning your Juki sewing machine from time to time will allow the machine to ensure optimal performance and longevity. A general rule of thumb suggests that you should clean your sewing machine at least once a month. However, if you use the sewing machine frequently or for heavy-duty projects, you should clean it more often than once a month.

Cleaning your Juki sewing machine entails that you should remove any lint or threads that are caught in the bobbin case or feed dogs. You can remove lint and threads by using a soft brush.

Also, use a sewing machine oil to lubricate the moving parts of your machine. Be sure to oil the needle bar, take-up lever, and other moving parts according to your machine’s instructions.

How To Perform A Full Service On A Juki Sewing Machine? 

When servicing your Juki sewing machine, it’s important to check and clean every component of the sewing machine. This will allow the machine to be fully clean and rid of dried oil and lint.

Here’s a step-by-step method to clean your Juki sewing Machine

Step 1: Clean out All Lint, Dust, And Old Oil

This is the first step when attempting to service your Juki sewing machine. You have to get rid of lint, dust, and old dried oil. Failure to do so can build up and cause problems for the sewing machine. 

Start by removing the lint from the machine. Use a soft brush to gently remove any lint that’s accumulated on the surface. You can also use a vacuum cleaner with a soft brush attachment to get rid of any lint that’s hard to reach.

Once the lint is gone, dust the machine with a soft cloth. Be sure to get into all the nooks and crannies, as dust can build up and cause problems.

Finally, it’s time to remove old oil from the machine, first place a few drops of sewing machine oil onto a clean cloth. Gently wipe down all of the metal parts of the machine with the oiled cloth until it’s fully clean.

Step 2: Check The Timing Belt/Motor Belt For Belt Tightness. 

It is important to check the tension of the timing belt/motor belt on your Juki sewing machine when servicing the machine. A loose belt can cause the machine to run slowly or unevenly, and can eventually damage the motor. 

To check the tension, first, make sure that the machine is turned off and unplugged. Then, find the tension adjustment knob (it is usually located near the front of the machine). With your hand, turn the knob clockwise to tighten the belt, or counterclockwise to loosen it.

Step 3: Check Motor Brushes And Make Sure The Motor Is Turning Freely

When servicing your Juki sewing machine, it is important to check the motor brushes and ensure that the motor is turning freely. This will help keep your machine running smoothly and help avoid any potential issues.

Step 4: Check All Shafts For Any Play Or Wobble

It’s important to check all shafts for any play or wobble when servicing your Juki sewing machine. This can be done by gently moving the shafts back and forth with your hands to feel for any movement.

If you find any play or wobble, it is important to adjust the shaft so that it is tight and secure before continuing to use the machine.

Step 5: Check The Wear Of All Bearings 

You should check the wear of all bearings. This will help ensure that your machine is running smoothly and efficiently. If you notice any signs of wear, be sure to replace the bearings as needed.

Step 6: Check The Bobbin Winder

Don’t forget to check the bobbin winder. This small but important part ensures that your bobbin is wound properly so that your sewing machine can function smoothly.

A properly functioning bobbin winder is essential to keeping your Juki sewing machine running like a well-oiled machine.

Step 7: Oil And Assemble The Juki Machine 

Once you’re done following all the above steps. The next step is to assemble the sewing back and oil every component before attaching it back.

It is also important to put every component back where it was removed. If you can’t remember how to assemble it, you can call a technician to help you with it.

Your Juki sewing machine is an important part of your sewing operation. Like any machine, it needs regular maintenance and servicing to keep it running smoothly. Here are some signs that your Juki sewing machine may need servicing:

  • Constant Tension Issues
  • The machine is making strange noises
  • The machine is skipping stitches.
  • The machine is not sewing evenly.
  • The machine is not feeding fabric evenly.
  • Needle hitting the bobbin

If you notice any of these signs, it’s important to take your machine in for servicing. A qualified technician can clean and oil the machine, and make any necessary repairs. This will help keep your machine running smoothly and prevent future problems.

How Do I Know When My Sewing Machine Needs Oil?

If you notice your sewing machine is making unusual noises, skipping stitches, or the needle is not moving smoothly, it may be time to oil your machine. Oiling your machine regularly will help keep it running smoothly and prevent expensive repairs down the road. 

Here are a few telltale signs that your sewing machine needs some oil:

1. The Machine Is Making Unusual Noises

If your sewing machine starts making strange noises, it’s a good indication that it needs oil. The parts of the machine may be starting to grind against each other, which can damage the machine over time.

2. The Machine Isn’t Sewing Smoothly

If your machine isn’t sewing smoothly, it’s another sign that it needs oil. The parts of the machine may not be moving as smoothly as there are no oil and metal components rubbing on one another.

3. Skipping Stitches 

Skipping stitches is a common problem that can be caused by a variety of factors, including a lack of oil in your sewing machine. 

If your machine is skipping stitches, it’s important to first check the oil level and, if necessary, add more oil. In most cases, this will solve the problem and you’ll be able to continue sewing without issue. 

4. The Needle Is Not Moving Smoothly

If your sewing machine is not moving smoothly, it could be a sign of your sewing machine needs oil. 


Juki sewing machines are some of the most popular machines on the market, and for good reason. They’re durable, reliable, and easy to use. But like any machine, they require regular maintenance to keep them running smoothly. 

A general rule of thumb suggests that you should service your Juki Sewing Machine every 6 – 12 months. However, if you use your machine frequently, you can change it to 2 – 3 months.
